I am sure I am not the first to want to use something with a bit more precision than my fat fingers to select areas for survey. It became even more apparent when I wear gloves. It has been plenty cold this winter and I find I am wearing gloves about 90% of the time flying. Big problem is; the darn screen needs your bare freezing fingers to actuate many things. So I poked around and really didn't find anything discussing it, except old Phantom series threads. I took the leap. I found this Active Stylus works just fine. I got it when it had a 20% coupon so it was even cheaper. There are piles of them available that seem to be the same one or slightly different that will work as well. I just took the chance for $12. There are active and passive stylus' The passive ones are soft rubber or a mesh about 1 cm in width. Not so accurate or better than my finger. I tried my Apple Pencil, nope it does ot work. The active ones have a finer point and the mesh passive as well. They recharge, perhaps my big dissapointment, with USB micro, not C. It seems to get around 10 hours of use, charges faily quickly. It does work on my iPhone Max and my iPad as well.

One version that worked

Oooh, that is clever.  Naturally I will need to poke about a bit to see where you pair the items. I see a bluetooth option, but never tired it except for phone pairing, which was hugely unsatisfying. I just found the stylus convenient for wearing gloves, since I can snatch it out of my jacket pocket quickly.
